About Phylo

Phylo is an applied research lab building agentic intelligence to accelerate discovery for every biomedical scientist. We believe AI agents will fundamentally transform how biomedical research is done. Our fast-growing team brings together researchers and engineers across AI and biology, commercializing the Biomni platform.

Our growing team brings together world class researchers and engineers across AI and biology. Backed by a $13.5M seed round led by a16z, Menlo Ventures and Anthropic, and advised by Nobel Prize laureate and pioneering biologists, Phylo is building the next generation of AI systems for the life sciences.

About the Role

We’re looking for an engineer to build and operate the core systems that power Phylo’s agentic AI platform in production. You’ll design and implement the distributed systems, compute environments, and service architecture that allow our AI agents to run reliably at scale — across cloud-native deployments and enterprise environments.

We are an AI-native engineering team: we use coding agents heavily, move fast, and hold a very high bar for engineering excellence.

What you’ll do as a Member of Technical Staff - System Engineering at Phylo:

• Design and build production systems that orchestrate agent execution and power AI-driven scientific workloads.

• Build and operate scalable, reliable infrastructure across cloud, hybrid, and on-prem enterprise environments.

• Develop systems for sandboxed execution, secure task isolation, and controlled compute environments. Design and implement security, access control, and compliance foundations suitable for enterprise deployments.

• Design and operate the storage and data systems behind large-scale scientific workloads, including distributed file systems, object storage, and databases.

• Partner closely with ML and science teams to translate computational workflows into robust, production-grade distributed systems.

What We're Looking For:

• 3+ years of industry experience in backend, infrastructure, or distributed systems engineering.

• Strong proficiency in at least one programming language (e.g., Python, Go, Rust, or similar).

• Experience designing and operating distributed systems in production.

• Deep hands-on experience with containerization and Kubernetes.

• Experience with infrastructure-as-code tooling (e.g., Terraform, Pulumi, or equivalent).

• Experience operating systems on at least one major cloud provider (AWS, GCP, or Azure).

• Hands-on experience building or operating large-scale distributed file systems, storage platforms, or databases in production.

• Comfort owning systems end-to-end in fast-moving, high-autonomy environments.

Nice to Haves:

• Experience in building R&D infrastructure at Pharma/Biotech.

• Experience supporting data-intensive scientific computing, bioinformatics, HPC, or ML workloads.

• Experience with job orchestration, task scheduling, or workflow engines.

• Experience with sandboxed or isolated execution frameworks (e.g., gVisor, Kata Containers, Firecracker).

• Familiarity with distributed storage, observability systems, or high-performance compute environments.
